I wanted to step in to update that we may not be doing this after all. It's not certain, but just as we were really getting into it, the fertility clinic I was a patient of sent out their monthly newsletter (that for some reason I never unsubscribed to) and they are starting a donor embryo program. We got on their waiting list to be sure we are involved when the program is ready to start. So for now this is our plan to try to add to our family. We know we can always foster later on, depending on how things work out. But I really want another baby and this seems like a good way to go about it.
